introduction: the purpose of this study was to evaluate the sealing ability of dentin bonding agents in root canals obturated with gutta-percha and mta. methods: forty-five single rooted human premolar teeth were decoronated so that remaining root portions were 12 mm in length. the samples were divided randomly into three experimental (n=13) and two control groups (n=3). all teeth were instrume...

Deoxyribonucleic acid base composition, deoxyribonucleic acid-deoxyribonucleic acid hybridization, and biochemical studies were performed on some enterococci from clinical sources of uncertain taxonomic position. Our results indicate that 6 human strains, a single clinical isolate and a strain from bovine mastitis are genetically distinct from each other and all other previously described Enter...

the main objective of this study was to investigate the effect of enterococci isolated from traditional lighvan cheese on the quality of iranian uf white during ripening. four samples of cheese were provided from four different cheese production units in lighvan region. strains of enterococci in these samples were isolated by standard microbiological methods and selective medium of kanamycin es...

Tylosin phosphate is a macrolide commonly administered to cattle in North America for the control of liver abscesses. This study investigated the effect of in-feed administration of tylosin phosphate to cattle at subtherapeutic levels and its subsequent withdrawal on macrolide resistance using enterococci as an indicator bacterium. Fecal samples were collected from steers that received no antib...

Here, we report the first draft genome sequence of Enterococcus thailandicus isolated from the feces of feedlot cattle in Southern Alberta.

Aim: To isolate and identify in a Chilean population, Enterococcus spp. from root canals with persistent chronic apical periodontitis (CAP) and to investigate the potential correlation between the bacteria and the observed clinical features. Methods: Twenty patients with indication for endodontic retreatment due to persistent CAP were selected. Data from patient general health and dental clinic...

Oritavancin (MIC50/90, 0.03/0.06 to 0.12 μg/ml) had potent activity against linezolid-resistant staphylococci, as well as Enterococcus faecalis and Enterococcus faecium (oritavancin MIC50/90, 0.015/0.12 μg/ml against both species). All linezolid-resistant isolates were inhibited by oritavancin at ≤0.12 μg/ml. These results confirmed the absence of cross-resistance between linezolid and oritavan...

Resistance to linezolid has been associated with a G2576U mutation in domain V of the 23S rRNA. We analyzed nine clinical isolates of linezolid-resistant enterococci and showed a clear association between the number of 23S rRNA genes containing this mutation and the level of linezolid resistance expressed.

BACKGROUND There is little information available in Chile on the distribution of Enterococcus spp in waste water and its implications in transmission of antibiotic resistance through the water cycle. Enterococcus spp are common in nosocomial infections and may spread antibiotic resistance through the food chain. AIM To determine the presence of antibiotic resistant Enterococcus spp in the sew...
